kconfig_lint: merge 'git grep' and 'grep' exclude dir and files
The code had originally been using standard grep to look through the coreboot tree for Kconfig symbols. When this was switched to git grep, the --exclude-dir options didn't work, and nothing was added to exclude the directories that shouldn't be searched for symbols. This resulted in invalid warnings as it searched directories that had Kconfig symbols for other projects. This merges the exclusion list for both the regular and git versions of grep for consistent behavior.
